Method for judging the master/slave computer consistent via static data or dynamic data

Abstract

The invention discloses a primary and secondary workstation consistency judging method by detecting the static data and the dynamic data. The steps are as follows: starting the static data or dynamic data consistency detection; suspending the static data or dynamic data primary and secondary synchronization; the primary workstation collects static data or dynamic data, calculates the calibration value and sends the calibration data to the secondary workstation; the secondary workstation receives the calibration data, collects data according to data types, calculates the calibration value and compares the result with the calibration value of the primary workstation; if the two calibration values are equal, the primary and secondary data are considered as the same; if the two calibration values are different, the primary and secondary data are considered to be not consistent and the secondary workstation sends the consistency detection result to the primary workstation; the primary and secondary synchronization is restored. The invention can detect the synchronization of the primary and secondary workstation dynamically at real time. When the primary and secondary data are not consistent, the inconsistency can be warned and recorded in time and the primary and secondary data consistency can be restored automatically, which is convenient for locating the inconsistency fault and shortening the fault location time.

Description

technical field [0001] The invention relates to a communication technology, in particular to a method for judging the consistency of master and standby machines through detection of static data or dynamic data. Background technique [0002] In embedded communication equipment, in order to improve the reliability and security of the system, the main control board is often provided with the main and standby working mode. In the system of the main and standby working mode, under normal circumstances, one main control board is in a normal working state (called the master), while the other main control board is in the standby state (called the standby machine). When certain conditions are met, the main control board that was originally in the standby state will turn into the active state (this process becomes the active state). standby switchover) to ensure the normal and stable operation of the system. Before the active-standby switchover occurs, the standby machine should keep...

Problems solved by technology

However, in practical applications, the implementation of the master-standby control logic is more complicated, and the master-standby functions are often prone to failures, and the faults related to the master-standby functions are difficult to locate and solve. The data and status of the host are not correctly synchronized, resulting in failure of the system to work normally or even business interruption after the switchover
